      • setDefaultImports

        void setDefaultImports​(java.lang.String[] optionalDefaultImports)
        "Default imports" add to the system import "java.lang", i.e. the evaluator may refer to classes imported by default imports without having to explicitly declare IMPORT statements.

        Notice that JDK 5 "static imports" are also supported, as shown in the following example.

        Example:

             sc.setDefaultImports(new String[] {
                 "java.util.Map",                          // Single type import
                 "java.io.*",                              // Type-import-on-demand
                 "static java.util.Collections.EMPTY_MAP", // Single static import
                 "static java.util.Collections.*",         // Static-import-on-demand
             });
      • setClassName

        void setClassName​(java.lang.String className)
        Set the name of the generated class. Defaults to DEFAULT_CLASS_NAME. In most cases, there is no need to set this name, because the generated class is loaded into its own ClassLoader where its name cannot collide with classes generated by other evaluators.

        One reason to use this function is to have a class name in a non-default package, which can be relevant when types and members with DEFAULT accessibility are accessed.

      • setExtendedClass

        void setExtendedClass​(java.lang.Class optionalExtendedClass)
        Set a particular superclass that the generated class will extend. If null is passed, the generated class will extend Object.

        The common reason to set a base class for an evaluator is that the generated class can directly access the base superclass's (non-private) members.

      • setExtendedType

        @Deprecated
        void setExtendedType​(java.lang.Class optionalExtendedClass)
        Deprecated.
      • setImplementedInterfaces

        void setImplementedInterfaces​(java.lang.Class[] implementedInterfaces)
        Set a particular set of interfaces that the generated class will implement.
      • createInstance

        java.lang.Object createInstance​(java.io.Reader reader)
                                 throws CompileException,
                                        java.io.IOException
        Scans, parses and compiles a class body from the tokens delivered by the the given Reader, then creates and returns an instance of that class.
        Parameters:
        reader - Source of class body tokens
        Returns:
        An object that extends the optionalExtendedType and implements the given implementedTypes
        Throws:
        CompileException
        java.io.IOException
